Something not working, or a question about the dive? The answers below cover the most common ones. If yours is not here, email us at noahmiller.dev@gmail.com and tell us your phone model and the app version (shown in the Log tab, under About).
Open the Log tab, scroll to Support the dive and tap Restore purchases. Use the same Apple ID or Google account you bought with. The app tells you what it restored, or that no previous purchase was found for that store account.
Premium is a one-time purchase, not a subscription. It removes the full-screen (interstitial) ads for good, and every bonus (double haul, ballast, sonar ping, crates) becomes one tap with no video.
If the store cannot be reached, the shop says why and shows a Retry button. Check your connection and try again. Nothing is charged when a purchase does not complete. Payments and refunds are handled by Apple or Google, so refund requests go through the App Store or Google Play.
Yes. Diving, catching, the bestiary and upgrades all run on your phone. Premium is remembered on the device, so it works offline too. You need a connection only to watch an optional video, to buy, or to restore a purchase.
Your submersible keeps diving while you are away, up to the limit of its tanks: 2 hours to start, plus 30 minutes for each Tanks upgrade. Time beyond that limit is not banked, and the app tells you when your tanks filled up so you are never shorted silently.
Progress is stored on this device only. There is no account and no cloud save, so progress cannot be exported or moved to another phone. Premium can always be restored on a new phone (see above).
Open the Log tab and tap Reset all progress at the bottom. This erases your bestiary, pearls and every upgrade, and it cannot be undone. Purchases are kept by the app store and survive a reset. Deleting the app also removes everything it stored.
Ads come from Google AdMob and are limited to a family-friendly (PG) content rating. Most are optional rewarded videos that you choose to watch for a bonus. The free version also shows an occasional full-screen ad, spaced at least 4 minutes apart. Premium removes the full-screen ads.
Open the Log tab and tap Ad privacy choices under Privacy & Ads to reopen the consent form. On iPhone you can also change tracking permission in the system Settings app, and on Android you can reset or delete your advertising ID in system settings.
Full details are in the privacy policy.
